This invention rel; to automatic fleet valve mechanism for controlling the outlets oi oihtiinlts, the main object ol the in'i'ention being to pro it simple and etl'ect-ive constructiou el 'wlve device adapted when the out-flowing oil hills to presl ed level to close the outlet, so to pre' at the same from con!inunicetin with atmosphere entrance into the and permitting air to have pipeline end thus Herding or obstructing the llowoloil ch 1h g;

The inn lion irll'iill'fl' for its object to provide means for locking the Vdl," in closed. position and r rising such leeldn; means when the tank end it is desire;

"unplied to its normal. lc to reset the valve for action. With bl l other e ecis in view the invention (1 oi the construction and combination of parts reii "ter fully described mid claimed, the :iceoiupenyin drawings, in which-- Figure 1 is a. sectional view el en oil-tank provided with the valve at the limit of its upward movement. Fig. 3 is :i sectioniil view through the tank, (liscluirge-nipe, and valve and showing the outl t sealed by the valve end the. latter locked in closed position. Fig; is a detail cross-section through the valve and discharge-pipe on the line 3 of Fig. 4 is it perspective viev. ii the vailx ind locking mechanism. l ig is a. detail view'or' the suppiMing-block.

Referring now more particularly to the drawings, the numeral l designates an oiltiink of any prelcrred size :Ulll construction, and 2 :in oil-discharge pipe extending horizontally into the bottom thereof mid closed at its inner end by :i cup I; end having at sonic suitable point within the tank on outlet connection 4. They pipe is supported within the tank by :1,insuring-block .3, having {L11 opening through which the pipe cxtendse-nd which also serves its support for the controlling-v l'vo i3 'llicviilvc ii is shown in the present instance in the form of an oblong Specification of Letters ?stent.

rectangular block of wood or other suitable material which is hinged or pivoted at its lower end, as at 7, to the block and is adaptcd-to contact with suitable stop members 8 l on the block at the limit of its 11 ward movement, in which it assumes, as s iown in Fig. 1, a position slightly inclined reerwardly irom'tlie vertical in order that it may swing freely downward by gravity when the oil in the tank lowers. The valve carries a suit ably-arranged float 9 to adapt it to rise when free for movement with the oil when the tank is iilled endis provided 11 on its rear surface with a disk or plate 10, of elt, rubber, or othe' suitable material, to seat upon and close the outlet 4 when the valve is in lowered position. Cl 1e pert-s thus far described are so combined end arranged that upon the downward tilting of the valve to'horizontal position, shown in Fig. 2, the disk will he outlet 4. just prior to the leveling eve of the oil with the top of the their point of intersection to pivots ly-engage the cooperating bolt 15, as indicated at 16 and the free ends of the jaws are bent to provide lapping: portions 17 and diverging extremities 18. The arms 13 and 14 extend laterally beyond the valve and .are thence bent forwardly and pr ovided at their free ends with eyes 19 for connection with cords 20, the said cords 20 being attached to a. common operating rope, chain, or cable 21, passingto the outer side of the tank over a guide sheave or pulley 2 The pivoted ends of the jaws and arms are arranged between spaced guide-plates 23, fixed to the rear side of the tree and of the valve and the jaws are limited in their opening movement by stoppins 2 carried by said plates.
